The goal of the Hawk project is to develop a language for expressing highly abstracted specifications of modern microprocessor designs, to provide design teams with the ability to dynamically explore a wide range of design choices. The Hawk language is Haskell plus the Hawk library. The original link at http://www.cse.ogi.edu/PacSoft/projects/Hawk/ seems to be no longer live.

Chortl is an extremely simple Haskell EDSL for hardware description. Chortl supports multiple backends. The current backend generates Verilog, and is intended for FPGA designs; near-future intent is to implement backends to generate C, and to provide graphical circuit diagrams. Chortl features include simplicity, a notation reasonably comprehensible by HW folks, the ability to define custom "components" such as adder trees in full Haskell, simplicity, and simplicity. Chortl is in a very early stage of development, so feedback and help are greatly appreciated.
